Combine butter, brown sugar, honey, and eggs in a large bowl and mix well. Stir in pumpkin. Gently fold in dry ingredients, alternating with the raisin/juice mixture. Stir in the pecans.

Generously fill muffin pan. Bake until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. (Bake baby muffins about 15 minutes.) Cool muffins in tins for 15 minutes, then remove from tins and serve warm, or let cool on wire racks. Store in an airtight container for up to three days or freeze.
